By the way, some good reading for you on aiptasia http://wetwebmedia.com/marine/inverts/cnidaria/anthozoa/aiptasia/aiptasia.htm
one anemone is fine and fish can avoid it but when there are dozens the chance of a brush or encounter are increased.Thanks from here too. Since theyre easily gotten rid of, I`ll definitely leave it and watch what develops.Doesnt seem to bother the crabs or snails. I`ll check with you all befor I add any more life to the tank.
I thought all anemonies could sting and the fish know it and leave them alone. ?
